ABSTRACT:
This invention relates to a liquid-liquid process for treating a sour hydrocarbon fraction. The process comprises contacting the hydrocarbon fraction in the presence of an oxidizing agent with an aqueous solution containing ammonium hydroxide, a metal chelate and an onium compound selected from the group consisting of quaternary ammonium, phosphonium, arsonium, stibonium, oxonium and sulfonium compounds. A preferred onium compound is a quaternary ammonium compound with an especially preferred compound being a quaternary ammonium halide. This invention also relates to a catalyst comprising an aqueous solution containing ammonium hydroxide, a metal chelate and an onium compound, for oxidizing mercaptans contained in a sour hydrocarbon fraction. The aqueous solution which is the catalyst can also be used to improve the activity of a fixed bed mercaptan oxidation catalyst.
